The aspects are described below in order to explain the present invention with reference to the figures. According to one aspect of the present invention, the 'annotation documents' include all documents described in the annotation language, such as HTML or XML, and documents in which written source codes - in an instruction language or Java they are linked or inserted and even represent annotation resources, such as files linked to an annotation document. In other words, the annotation document serves as an application program for reproducing AV data in an interactive mode and contains interactive contents that will be presented visually together with the AV data. Figure 1 is a schematic diagram illustrating a reproduction system, according to one aspect of the present invention. Referring to Figure 1, the reproduction system includes a DVD 300, which is a data storage medium according to an aspect of the present invention, an apparatus 200 for reproducing data, a television set 100, which is a visual display device according to an aspect of the present invention, and a remote control 400, which is a user input device. The remote control 400 receives a control command from a user and transmits the control command to the apparatus 200 to reproduce the data. The apparatus 200 for reproducing the data includes a DVD unit 201 for reproducing the data of the DVD 300. When the DVD 300 is loaded in the DVD unit 201 and the user selects the interactive mode, the apparatus 200 for reproducing the data reproduces the AV data recorded on the DVD 300 in the interactive mode using the annotation document corresponding to the AV data and transmits the reproduced AV data to the television set 100. The television set 100 visually displays a score screen obtained using the Annotation with an AV screen obtained when playing AV data. The AV screen is inserted in the annotation screen. Here, the interactive mode represents a visual presentation mode in which the AV data, are reproduced, are visually presented in a visual presentation advantage defined by the annotation document, that is, a visual presentation mode in which the screen AV visually presents the AV data, and inserted into the annotation screen. Here, the AV screen represents a visually presented screen on the display device, ie, the television set 100, when the AV data is played back, and the annotation screen represents a screen presented visually on the display device when the annotation document is interpreted. A screen presented visually in an interactive mode is called an interactive screen. The interactive screen includes the AV screen and the annotation screen. A video mode represents a conventional data reproduction mode defined by DVD-video standards, that is, a mode in which only the AV screen obtained when reproducing the AV data is presented visually. In one aspect of the present invention, the apparatus 200 supports both the interactive mode and the video mode. The apparatus 200 provides a parental level adjustment knob or a screen display menu that enables the user to set a parental level.

In addition, the apparatus 200 can receive the data from and transmit the data to other devices through a network, such as the Internet. Fig. 2 is a block diagram of an example of the apparatus 200 for reproducing the data, in accordance with an aspect of the present invention. Referring to Figure 2, the apparatus 200 includes a reader 2, a controller 3, an AV decoder 4 and a mixer 7. A display machine 5 is provided in the controller 3.

The reader 2 controls the optical pickup in response to a control signal sent by the controller 3 so that the optical pickup reads the AV data and the document DVD annotation 300. The AV 4 decoder decodes the AV data read from the DVD 300. In a case where the AV data has been recorded on the DVD 300 in accordance with DVD-video standards, the AV 4 decoder decodes AV data following the DVD-video standards. From the software point of view, the presentation machine 5 in the controller 3 is a machine for interpreting and executing an annotation language or a client interpretation program language such as JavaScript or Java. The presentation machine 5 may also include several plug-in devices. Files of various formats included in the annotation document or linked to the annotation document can be opened by these plug-in devices. For example, the Windows Media Player may be opened by the presentation machine 5 to play AV data files of Windows Media Player. In addition, the presentation machine 5 can open predetermined data, such as annotation documents, from other devices through the network. The presentation machine 5 interprets the annotation document read from the DVD 300 in order to reproduce the AV data recorded on the DVD 300 in the interactive mode. In other words, the presentation machine 5 identifies the parental level established by the user for the apparatus 200 and interprets the annotation document considering the parent level. In one aspect according to the present invention, five different parental levels are provided, namely G, PG, PG13, R and NC-17, which are the same as those defined by the DVD-video standards for compatibility. The annotation documents, according to one aspect of the present invention, are provided to reproduce the recorded AV data on the data storage medium in accordance with the DVD-video standards in an interactive mode, and the annotation documents are provide in accordance with the parental levels for compatibility. The presentation machine 5 uses an application program interface (API) to identify the parent level established by the apparatus 200. The presentation machine 5, however, can use the API defined by conventional interactive DVD-video standards, it is Say, Interactive API Specification. The example of the API is the following. 1. Property Parental level 2. Summary Return a value of current parent level 3. Return values Integer of 1 byte of ECMASCript Number Signed Parental level that varies from 1 to 8 when 1 = G, 2 Reserved, 3 = PG, 4 = PG13, 5 = Reserved, 6 = R, 7 = NC-17 and 8 = Reserved. The user can set the parental level in any of 1, -3, 4, 6 and 7. The presentation machine 5 can identify the parent level set for the apparatus 200 to reproduce the data using API "Parental Level" properties. .

The mixer 7 mixes the AV data stream with the interpreted annotation document so that the AV data stream can be displayed visually in the visual display window defined by the annotation document; in other words, the AV screen can be inserted into the screen of the annotation document. Later, the mixer 7 sends the result of the mixture to the television set 100. Figure 3 is a diagram illustrating directories of data recorded on the DVD 300 in which data is recorded, according to a first aspect of the present invention. Referring to Figure 3, a root directory includes a video directory VIDE0_TS in which the AV data is stored. In the video directory VIDE0_TS, a VIDEO_TS navigation file is stored. IFO that contains navigation information of all sets of video titles. Then, a VTS_01_0.IFO navigation file containing the navigation information of a first set of video titles, and AV data VTS_01_0 are recorded. VOB, VTS_01_1. VOB ..., which is the set of video titles. Each of the data plurality AV VTS 01 0.VOB, VTS 01 1.V0B, ..., is a video title, that is, a video object. Each VOB of video objects includes a VOBU video object unit, which is a package of a navigation package, a video package and an audio package. A detailed structure of VlDEO_TS has been described in 'DVD-video for Read Only Memory Disk 1.0' which handles DVD-video standards. An interactive directory DVD_ENAV is provided as a subdirectory of the root directory. In the DVD_ENAV interactive directory, annotation documents are stored to support an interactive mode. In particular, in the DVD_ENAV interactive directory, a STARTUP.XML start document and INDEX annotation documents are stored. ML and WARNING.XML to selectively display a parental level. In addition, other annotation documents, that is, files inserted in STARTUP.XML, INDEX.XML and WARNING.XML, are also stored in the interactive directory DVD_ENAV. The STARTUP.XML start document contains the parental level information and link information. In one aspect of the present invention, the parental level information is a parent level written in the STARTUP.XML start document, and the link information is the annotation document information indicating whether the parent level established by the user is higher or lower than the parent level written in the start document STARTUP .XML. An example of the STA TUP start document. ML is next. < ? xni) version- '1.0"V> <!

According to the meta-information and link information, WARNING.XML is presented visually on the screen when the parental level set for the apparatus 200 to reproduce the data is 4 or less, and INDEX.XML is presented visually on the screen when the parent level exceeds 4. The presentation machine 5 identifies the parent level set in the apparatus 200 to reproduce the data using the API that has been described above and interprets annotation documents using meta-information and link information written in a document of annotation designated as a start document. Figure 4 is a diagram illustrating directories of the data recorded on the DVD 300, according to a second aspect of the present invention. Referring to Figure 4, the root directory includes two subdirectories, ie a VIDEO_TS video directory where the AV data is stored and the DVD_ENAV interactive directory where the annotation documents to support the interactive mode are stored. The video directory VIDEO_TS shown in figure 4 is the same as its counterpart shown in figure 3, and in this way its description will be omitted. In the DVD_ENAV interactive directory, a start document STARTUP .X L is stored. In addition, the interactive directory includes subdirectories G, PG, PG13, R and NC-17 that refer to different parental levels. Each of the subdirectories G, PG, PG13, R and NC-17 contains an INDEX annotation document. ML that corresponds to the parental level. In addition, in the DVD_ENAV interactive directory, other annotation documents are also stored, that is, files inserted in STARTUP.XML or INDEX.XML. In the start document STARTUP.XML, link information is stored. In an aspect according to the present invention, the link information includes annotation document information indicating the parental level set by the user for the apparatus 200 to reproduce the data.

The CSS file may be included in the annotation document instead of being generated separately from the annotation document. In an aspect according to the present invention, the CSS file contains visual presentation rules information. The visual presentation rules information is written according to a "© media rule" style defined by CSS rules. An example of "© media rule" that defines visual presentation rules for objective media is as follows. @niedia print. { BODY í font-size: lOpi} 1 @media screen. { BODY (font-size: 12pt.).) @ Media screen, print. { BODY { line-height: 1.2} According to the above "© media rule", target media having a font size of 10 and a spacing between lines of 1.2 are printed and displayed visually on the screen with a font size of 12 and the space between lines of 1.2. In one aspect of the present invention, the visual presentation rules information written in accordance with the CSS standards is as follows.

Here, OparentalLevel-display indicates that an element that has an attribute value of "class" of 3, 4, 6 or 7 sets the parameters "visual presentation" and "visibility" as "box" and "hidden", respectively, when the parent level is G. In particular, if the parameter "visual presentation" is set as "frame", the frame regions are generated and continue to exist even when the frame regions are not physically seen. If the parameter "visual presentation" is established as "none", the generation of all the tables is prohibited in such a way that the disposition of the annotation documents is more prone to be revoked because even unseen frame regions can help to dispose the annotation documents. In other words, by adjusting the "visual presentation" parameter as "frame", the annotation documents can be arranged well. The "visibility" parameter is used to determine whether these generated frame regions are going to be seen or not. An example of the INDEX annotation document. XML that includes the information of visual presentation rules according to the CSS rules is the following.

As shown in the previous example, the parent level value is assigned to each element in the "body" of the INDEX.XML annotation document as an attribute value of "class". If it is presented visually, each element is determined based on the OparentalLevel-display visual presentation rules information.

An example of the INDEX.XML annotation document and its visual presentation rules information, which is provided as an individual unit following the CSS norms, that is, INDEX.
